Species Guides

Neolecanium cornuparvum(Magnolia scale)

Neolecanium is a of soft scale insects ( Coccidae) established by Parrott in 1901. The genus includes that are pests of woody plants, notably magnolia scale (Neolecanium cornuparvum), which is monitored by the USA National Network for phenology-based pest management. Like other soft scales, members of this genus possess a waxy protective covering and feed on plant phloem. The genus is included in the Pheno Forecast program, which uses heat accumulation models to predict insect development and optimize control timing.

Human Relevance

The includes economically significant pest . Neolecanium cornuparvum (magnolia scale) is specifically targeted by the USA National Network's Pheno Forecast program, which provides daily maps and six-day forecasts to help tree care , arborists, foresters, and natural resource managers optimize timing of pest control efforts. The Pheno Forecast system uses heat accumulation models to predict when this pest reaches vulnerable developmental stages, enabling more economical and environmentally targeted management.

More Details

Phenology Forecasting

Neolecanium is one of twelve pest for which the USA National Network provides Pheno Forecast maps. These maps use temperature-based heat accumulation models with species-specific base temperatures to predict developmental events across the United States. The program was developed in consultation with experts from USGS, USDA, National Park Service, universities, and the landscaping and arborist industries.
